Pressure washing system for wet wells

摘要

Herein is disclosed an in-situ system for automatically washing the walls of a wet well. The system includes a high pressure water pump coupled to a plurality of elongated high pressure water spray heads mounted along the walls of the wet well. The high pressure water spray heads are each coupled to the water pump via a solenoid valve which is in turn coupled to a control panel. The control panel is configured to operate the spray heads one at a time so that the wet well is washed by operating only one spray head at a time. The system uses standard municipal water line as a water source and uses inexpensive motors, pumps and fittings.

主权项

1. A system for washing down a walls of a wet well, the system comprising:
a. A high pressure water pump for creating a flow of high pressure water; b. An elongated header mounted adjacent the wall of the wet well, the elongated header dimensioned to extend along a length of the entire wall such that the elongated header spans the entire wall; c. A plurality of high pressure water nozzles formed on the elongated headers, the high pressure water nozzles positioned on the elongated header to wash a portion of the wall with high pressure water; d. The elongated header being coupled to the high pressure water pump via a solenoid valve, the solenoid valve being coupled to a control unit, the control unit configured to open and close the solenoid valve; e. wherein the elongated header is mounted to the wall by a pair of mounting brackets configured to permit the elongated header mounted thereto to pivot along a long axis of the elongated header, the system further comprising a pivot motor coupled to the elongated header for pivoting the elongated header such that the high pressure nozzles formed thereon are pivoted up and down in a sweeping fashion when the pivot motor is activated, the pivot motor being coupled to the control unit which is configured to activate the pivot motor in coincidence with the opening of the solenoid valve.
